Sample Day 3

Bike Testing

Be sure your body is rested, this is like a short race effort. Allen and Coggan's protocol is as follows in Exercises & Intervals be sure to hit view intervals

 20 MINUTE WARM UP easy

 3 X 1 MIN SPIN UPS WITH 1 MINUTE REST (increase intensity and rpms to 100-120rpm)


 5 MINUTES HARD (This should be a practice for the main set, find your level of intensity that is the max sustainable pace)


 20 MINUTE TIME TRIAL EFFORT (max sustainable pace in self- selected cadence of choice)


Sample Day 4

25 min Recovery Run/walk

25 mins very easy cap top of Z1 would like half of this as a walking effort and preferably on a soft surface to mitigate ground reaction force and impact stress. This is a great workout to do on a hiking or nature trail. Don't get sluggish in cadence because of the easy nature of this workout. Goal Cadence should still be around 90 steps per minute.

Think of this as sharpening the saw. It should make you feel better not trying to get anything accomplished here but just facilitating recovery
